The report of the nocturnal greffier.
Hello to all,
I join the Master (whose cybernetic report appears at the end of this mail) to wish you a good vintage 2006 with many checks and problems for 2006 as usual.
Yesterday's session was honoured, in addition to the faithful members, by the presence of the now specialist of the P.G., I named K'ptain Benoît.
The greffier having arrived a little late, he was very surprised to find a Circe Assassin on the wall chessboard, and wondered for a moment if the dates of the
had not been changed. This was not the case, fortunately.
To begin the agape, a not too complicated appetizer study with a nice manoeuvre and a superb ending
.
1 - White to play and win
W.: Kb4, Qd1, Bb8, pa7, d4 and d6
B.: Kc6, Qa6, Ba1 and e8, Nb5, pb7
The next one is amazing, black has 4 (!) more pieces
2 - White to play and draw
W.: Kh8, pd6, d7, e6, f7, g4 and h2
B.: Kg6, Rb7 and d8, Bc3 and g8, pb5, b7, g5, g7 et h3
Master's words
A "course of the marquis" without coco strike : what a rest, by way of new year wishes ... which excites Guy's verve, who has become an expert in composition ... of köko !
The situation is more complicated when it comes to the mathematical exercises : Daniel's (usual) laziness in this matter (a diagram inadvertently fell out of his pocket ... which I had to give him more than two years ago !) is compounded by that of the aforementioned Guy, who is nevertheless an exceptional "solver", which contrasts with his bunny-ness as a composer.
All this leads me to increase the dose.
And three retros: 2 PJs -- fashion -- & a tradi, the weak point of the decade which I think it's a good idea, ipso facto, to detail (serious readers should, after clicking on "Yarosh", not read the text, click on "diagram" and try to construct the position).
A "killer" circe for good measure and the "problem that drives you crazy" (including the king circus) for Guy who feels he is not crazy enough.
Two studies of the "great Afek", who is going on 54, a little less than I thought, and a lot more than Guy thought.
In the same vein, Anand's first victory over Kasparov was in 1991, as I claimed (and Benoit disputed). It is true that I had committed an unforgivable error: I had spoken about Reggio-Emilia 1991, whereas it is in Reggio-Emilia 1992 that Anand beat (a second time, therefore) the famous retiree, bringing the score to 2-1.
A masterpiece by a much younger world star of etude composition, and another by the same, already on display, for those with short memories.
Lots of wild variants (and attempts to rip off dynamic listeners) in today's part:
Peter's "refutation" of 14...Ke7 is not (yet) convincing.
the "refutation" by all (!) of 17...Qd6 by 21 Rad1 e4 and now, instead of 22 Qa1 Kf8 23 Qe5 (given falsely as white advantage in 65/391, Shulman-San Segundo 1995-6 )
23:.. Qxe5 24 fxe5 a4!!, black advantage, instead of 24...Kg8?
Finally the attempt 22 Rd4 (f5!) or 22 f5 ( Kf8 23 Rd4 Re8 24 Rf4 Bc8! or 23 ... Bc8 24 Rxe4 Bd7 is not more so.
ditto for 20...Qd6 21 Qc2 g6! 22 f4 Kf8 satisfactory for Black.
the contestation of White's win after 27 e4 ... 30...Rc8? ... 36 Qc7! is obviously derisory, White having on 36...a2 37 Qxd8 Qxc5+ 38 Kh1 a1Q 39 Bxb7 (played "live" but Qh4! or Qg5! too) Kxb7 40 Qh4 Qb5 41 Qf2 (instead of my 41:Qe1?? played as a half-blind simultaneous blitz)
Three curiosities to end it all.
Excellent reading, assuming you have recovered from the traditional orgies.
AV
3 - White to play and draw
W.: Ke4, Rh6, pc5
B.: Ke7, Rf2, Nb7, pb4
Would you believe it, it ends with a zug!
Today's game is on the same opening as the previous "normal" course
4 - game of the day
1. d4 d5 2. c4 c6 3. Nc3 e6 4. Nf3 dc 5. a4 Bb4 6. e3 b5 7. Bd2 a5 8. ab Bxc3 9. Bxc3 cb 10. b3 Bb7 11. d5 Nf6 12. bc b4 13. Bxf6 Qxf6
14. Qa4+ Nd7 (14. ... Ke7 needs to be explored)
15. Nd4 e5 16. Nb3 Ke7 17. Be2 Rhc8 18. Rd1 (18. Bg4 Qd6 quiet)
Nc5 (Qd6 is interesting) 19. Nxc5 (19. d6+ Kf8 [Qxd6 Nxc5] 20. Qb5 Bc6) Rxc5
20. 0-0 Ra6 (Qd6 or better Kf8 avoid some later worries)
21. Qc2 a4 22. f4 b3 Qe4 Kd6 24. Qxh7 e4 25. Qxe4 a3
26. Qd3 b2 27. Qb3 (27. e4 Kc7 [Kd7 28.e5 Qb6 29. Bg4 Kc7 30 d6+ Kd8 is steep] e5 Qb6 29. d6+ Kb8 30. Qd4 Bc8 and Black is well)
27. ..Bc8 28. Qb8+ Kd7 29. Bg4+ Kd8 30. d6 a2 31. d7 resigns
For dessert, our friend Guy presented us with some of his compositions, but as they are not yet published, they will not appear in this report.
The works in question show that undoubtedly, even if some imperfections remain, we are in the presence of a great talented creator. To be continued.
The years to come will show us indisputably that he was even a very talented creator!
To start the digestion, an "official" work by another great creator.

5 - serial h#6, Alsacian Circe, 2 solutions.
serial helpmate : black plays n moves in a row to help white checkmate him.
Alsacian Circe : A captured piece is reborn on its original square and the rebirth of the piece must be combined with a strict legality of the position. If the position is not legal, then the capture is illegal.
2 solutions : there are 2 distinct keys to solve the problem
W.: Ka1, Bh3, pa4, b3, c5, c6, d2, e4, e7 and f2
B.: Kc7, Nd8, pb4, b7 and h2
You will of course have recognized MC under the qualifier of the very great creator.
To help you a little, the promotion of the h2 pawn in Q or R is impossible because of the Ka1.
The following is a composition of Yves Cheylan in Patrouille chess, it is very destabilizing, even if you know the genre !
6 - s#2 Patrol Chess
selfmate : white plays and forces black to checkmate
Patrol chess : the pieces move normally but, to capture, they must be at the start of the move under the protection of a piece of their camp.
W.: Kb1, Rc2 and g7
B.: Ka1, Bh8, pc4
To rough it up a bit, Rg7 is pinned. If it moves, the Bh8 protects the Ka1 and Kxb1 becomes possible.
To finish, a foray into the Parrain Circe (no relation to the Sicilian defence)
7 - serial h#9. Parrain Circe, 2 solutions.
Parrain Circe : a captured piece hangs over the capture square and makes an equipollent move to the piece playing immediately behind.
W.: Kb5, Ne4 and f5
B.: Kd5, pe5 and e6
it's quite cute
It remains for me to wish you a good reading and to give you an appointment soon for the corrections of the Master and in 2 weeks for the next session.
Yours sincerely
